Imaging photon detectors (IPDs) can perform down to light levels of a few photons/sq cm/sec; this is 5-6 orders of magnitude more sensitive than civil and military low-light TV systems, and obviates the use of cryogenically cooled arrays which can destroy the linearity of cooled CCDs. An account is presently given of the characteristics of vacuum-tube IPDs with resistive anode, with centroiding CCD, and with wedge-and-strip readout, in order to evaluate their comparative advantages. All three readout system types are in principle capable of covering the entire EM spectrum, from MeV photons/particles down to less than 1 eV, and share similar limitations in count rate, counting efficiency, and resolution.
